8 Claims.

This invention relates to caps adaptable for sealing containers such asmilk bottles, jars, and

other types ordinarily used in packing and vend-v ing jams, peanutbutter, or other commodities. It has for its objects to provide sealingmeans, inexpensive to manufacture and eflicient in use; to provide asealing means whichwill, in addition to effecting a perfect sealing, atthe same time provide protection for the exterior of the container atand near the point of sealing, so that the said adjacent exterior may beprotected from any contact with foreign substances; to provide a sealingmeans which is practically impossible to remove without leaving visibleevidence of the removal, yet which can be easily and readily removed byhand without the use of tools or other implements; to provide a sealingmeans of maximum effectiveness in the first instance, yet is impossibleto remove without showing visible evidences of its first removal; toprovide a sealing means which is usable and effective with or without aninner gasket; to provide a sealing means which will meet therequirements of the most exacting board of health regulations; toprovide a sealing means originally constructed in a. plurality of parts,but which, in assembled form, become integral; to insure effective meansagainst the refilling of original containers without visible evidence ofsuch refilling; to provide a, seal- 9 ing part, sufliciently sized towell cover and pro tect the container opening, thereby afiording ampleretaining space upon which to securely fasten the plural portion of thecomplete sealing means;

to provide a sealing member or disc, having therein on a line parallelto its outer circumference, a

series of triangular cuts, forming, but not detaching, a series offan-shaped pieces which may in turn be folded in the direction of theouter circumference of the sealing disc, so as to render the disc ofmajor bulk and thickness adjacent its exterior circumference, and of alesser and corresponding bulk at points within and parallel to saidexterior circumference, all for the. purpose of rendering of lesserthickness, that portion of the disc which contacts with the container atits greatest circumference immediately adjacent the containers opening,and of greater thickness at that portion of the disc which contacts thecontainer on the side of said greatest circumference which is positionedaway from the containers opening; to provide effective locking means forsecuring the said disc in position on the container; to number said cutsand fan-shaped pieces in proportion to the size of the disc, so as toremove '55 a substantial portion of the disc at its out out 1932, SerialNo. 62am area and fold same onto the exterior of the disc adjacent itsouter circumference, and thereby substantially increase the thickness ofsaid disc at said outer circumference; to provide an exterior ringmember of diameter substantially equal to the distance between one ofsaid openings in said disc, and the opening farthest therefrom on theopposite side of the disc; to provide an exterior ring sized to fitsnugly over the edges of the disc 'as they envelope the sides of thecontainer adjacent its opening, adaptable to function so as to forcesaid fan-shaped pieces in the direction of the outer circumference, andonto that portion of the disc adjacent said outer circumference;'tothereby securely anchor the disc in position upon and about the openingof the container by sheer force of its thickened outercircumferenceconflned within said ring; to provide a mode ofconstruction and application which produces a significant andoutstanding drum-like tautness at that portion of the disc which coversthe container opening; to provide a construction and method ofapplication, the various steps of which all function to co-operate to aneffective and'finished result in an apparent and integral merger; toinsure a unit construction by the application of a suitable adhesive tothe parts of the vice, rendering it unsuitable for further use; to

provide a seal of maximum eiilciency and attractiveness at a minimumcost of material; to materially increase the measure of sealeraccomplishment; to provide a sealer both neat and close fitting,eliminating elements such as the outstandirrg and overhanging partswhich easily become soiled and are otherwise objectionable; to provide asealer of major attractiveness which readily blends with desirable coloreffects, in lettering an ornamental design, for advertising purposes;and to provide the various otheradvantages and results made evident fromthe following specification.

I accomplish the objects of my invention by providing a member or disc,having therein on a line parallel to its outer circumference, a seriesof cuts, forming, but not detaching, a series of fanshaped pieces whichmay in turn be folded in the direction of the outer circumference of thesealing disc,- So as to render the disc of major bulk and thicknessadjacent its exterior circumference,

and of greater thickness at that portion of the disc which contacts thecontainer on the side of I said greatestcircumference which ispositioned away from the containers opening. I then provide an exteriorring sized to fit snugly over the edges of the disc as they envelop thesides of the container adjacent its opening, adaptable to function so asto force said fan-shaped pieces in the direction of the outercircumference, and

onto that portion of the disc adjacent said outer circumference.Optionally, I apply a suitable adhesive to the parts of the device wherethey contact parallel to the said exterior circumference of said disc.The application of such adhesive at said points, materially contributesto the impossibility of removing the device without visible evidence ofsuch removal. The sealing means herein described is applicable with orwithout an inner gasket, such use being optional. Said outer sealingring is provided on its-exterior with an incision which weakens itsstructure thereabouts so that a tearing pressure there applied, resultsin its removal and partial ruin, rendering it unsuitable for furtheruse.

The series of-fan-shaped pieces referred to may I optionally be foldedinwardly or outwardly onto the surface of the disc adjacent its outercircumference. That portion of the disc adjacent its outer circumferencemay optionally be fluted to better facilitate itscloser formation to thesides of the container adjacent its opening.

. to the exact details of construction herein set forth, but desire toavail myself of such variations the scope of and modifications as comewithin the appended claims.

Referring to the accompanying drawing which forms a part of thisspecification and in which similar letters of reference refer to similarparts throughout the various views, Figure 1 shows my improved device aspositioned on-the top of a milk bottle. Figure 2 shows .a half sectionof the bottle and cap shown in Figure 1. Figure 3 shows --Referringagain to the drawing, A shows the disc designated as E.

container. 13 shows the sealing disc. C shows the exterior ring. D showsthe fan-shaped pieces, cut from the sealing disc and folded onto andupon that portion of the disc adjacent its outer ciroumference as shownin Figures 5 and 6, said fanshaped pieces being cut from that portion ofthe During the process of application, the sealing disc B, firstprepared as shown in 'Figure 6, is

shaped by pressure into the form shown in Figure 5, with the fan-shapedpieces D, extending downwardly as shown in the direction of theoutercircumference of: the disc; Theexterior ring adhesive acts to makethe sealing disc and outer ring integral.

Having thus described my invention, I claim as new and desire to secureby Letters Patent of the United States of America:
